Problem with Kudos CDS from "employee experience starter kit"

[Z_Lukowski]

Hello,

Im fairly new, and wanted to try downloading some real life power apps

I've encountered this:

https://powerapps.microsoft.com/en-us/blog/powerapps-employee-experience-starter-kit/

After importing solutions and power querry custom data using instruction from the web page one of the apps, Kudos CDS

cannot load properly and in edit mode I've encountered about 140 different errors, aslo "undefined" when trying to reconnect to data sources:

Is the app broken or someone was able to start this PowerApp?
